FRICTION DRAFT-*RIGGING;

To all whom it may concern:

Be it known that I, ALBERT O. BUcKIUs, county, Illinois, have useful Friction Draftof which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal sectional view showing my improved draft-rigging applied to a car. Fig. 2 is a plan view, and Fig. 3 a longitudinal section, ofa modified form. Fig. 4 is a longitudinal section of another modifi- Fig. 5 is a perspective view of the spring-case of Iiig. 1. Flg. 6 is a'perspective view of one of the followers, and Fig. 7 is a perspective view of one of the friction memers or wedges.

My invention has relation to friction draft- 1" ings, and is desi ed to rovide asim e a d eificient draft-li g ging a? this charact dr; and the invention consists in the novel construction, arrangement, and combination of parts, all substantially as described, and pointed out in the a pended claims.

In the drawings, the numeral 2 designates Rigging,

3 is a yoke which extends rearwardly from the draw-bar and engages and is secured to the head 4 thereof.

Referring first to the construction shown in 1, the numerals 5 and 6 designate two followers placed face to face and having formed in their op sing faces a plurality of pockets 7, in whic are seated the frictional members or wedges 8, having the oppositely beveled surfaces 8 and 8 which coact with pockets 7. These followers mounted u n the intermediate portion of a central r or shaft 9, this portion being preferably uare or angular in cross-section. 10 is a rear follower, and 11 is a spring-case which actsas a front follower. Interposed between the followers 11 and interposed between the followers 6 and 10 are springs 13. The followers'10 and 11 are arranged between suitable stops or draftirons on the draft-timbers in any usual or suitable manner.

It will be readily seen that under either pulling or buffing stresses the followers 5 and 6 will-be compressed againstthe intermediate are slidingly Specification of Letters Patent.

friction members or wedgesS, thereby forcing the latter into close frictional contact with the central rod or shaft 9, the. friction the increasing stress. The rod 9 is preferabl made somewhat shorter A etween the two followers, so as to permit of a certain initial compression of the sprin before the friction members commence to f u ly act.

The construction shown in Figs. 2 and 3 is similar to that in Fig. 1, with the exception that I have shownsingle s rings 14 instead of the double springs 12 an 13, with an ordinary follower 15 in place of the spring-case 11. In this construction the followers are mounted upon the squared through-rod 9}.

In the modification shown in Fig. 4 I em- Iploy two pairs of followers 16 16 and 17 17, etween each of which are a, series of friction members or wedges 18, which are similar in their operation and arrangement to the friction -members 8 first described, a single spring 19 being interposed between the two sets of followers and the latter being arranged to slide on a s uare through-rod 20.

The advantages 0 my invention will be appreciated by those skilled in the art. The arrangement is a simple and effective one in its arrangement of friction members directly acted upon by the followers and takes up so little room that it can be readily applied to use in all cases where draft-riggings of the kind now commonly em loyed are applicable. The invention may e modified in many ways without departing from the spirit and scope of my invention as defined in the claims, since What I claim is- 1. A draft-rigging havin her, a pair of followers s idably mounted thereon, and a friction member seated between and engaged by the followersand acting upon the central member; substantially as described.

2. .A draft-rigging having a central memher, a pair of followers seated thereon, a plurality of friction members between the opposing faces of and engaged by the followers,

a central mem- .and spring mechanism acting upon the followers; substantially as described.

3. A draft-rigging having a yoke, spring mechanism therein arranged to be compressed by pulling and bufling stresses, a pair Ice of followers engaged by gaging the o a'n' arrange mechanism in t e on the central the spring mechanism, and a friction member'between and enposing faces of thefollowers to be forced a friction member; substantia yas described. 4. Adi'aft-ri v oke, a central friction member, a pair of f0 owers slidably mounted friction member and having formed with beveled walls, and a plurality of friction members having surfaces coactrng \with the central member, and beveled faces coacting with the beveled faces of the pockets; substantially as described.

5.' In a draft-riglging, a friction device consist' er shdingly mounted thereon,

pocketed faces and having ainst a central 1 having a yoke, a spr ng of a centra member, a pair of followass-.953

pockets or recesses in their opposing'faces,

and a lurality of friction members having 20 bevel faces coactm'g with the beveled walls of the pockets and fnctionally engaging the central member; substantially as described.

6. A draftrigging comprising a yoke, a central through-rod forming a bet, two pairs of followers seated on said rod and having interposed friction members, and a s ring interposed between the two pairs of fol owers; substantially as described.

In testimony whereof I have hereunto set 30 my hand.
